Course description

Explore the concepts behind View Components, learn how they’re put together as a combination of a class and a view, and find out how to create and use them. Get a feel for just how simple and straightforward View Components can be by still being as sophisticated as you’d like by taking a look at an example of an app that shows a way to reuse summary data throughout a website. Dig deeper into the details and build a new project that uses a View Component to display various lists of our dogs. Explore some interesting features of an ASP.NET Core application, including how to use Entity Framework Core to support the data that the View Component needs. Along the way, take a look at another example of using Dependency Injection, here in a View Component, and an interesting way to define that service.

Prerequisites

This course assumes that students have some programming background, and at least minimal experience with classic ASP.NET, C#, and Visual Studio. As with any such course, the more experience you bring to the course, the more you'll get out of it. This course moves quickly through a broad range of programming topics, and is focused on using the .NET Framework with C#. The course also assumed that you are well familiar with how to use the version of Windows that you are running. For example, the course might say simply open a browser duo; without explaining how to do that. You should also be able to navigate the folder hierarchy using Windows Explorer.
